To all 'whom it may concern: I f Be it known that we, JAMES WAGNER, a subject ol the Emperor ol' Austria-Hungary, residing at Cleveland, in the-county ol' Cuyahoga and State of Ohio, and ANDREW S'raNAi, a citizen oi the United States of America, residing at Cleveland, in the county of Cuyahoga and State oi Ohio, have invented certain new and useful Improvements in Water-iliotors for Washing-Machines; and wedo hereby declare the folto be a lull, clear, and exact descri' tion ofthe invention, such as will enab e others skilledin the art to which it pertains to' make and use the samer, y

This invention relates to' motors and especially hydraulic motors of the reciprocating type. adapted particularly for operating washing machines and the like.

More specifically the inventionrelates to the arrangement and construction of. the valve and valve o ierating mechanism oi' the motor, and has ior'oneI of its object-s the provision of a valve which is very simple in construction'and effective in its o ie'ration, and which will be quickly thrown irom one position to the other at the proper time.

A further ob'ect is the revision of a motor which will be )ractica lyno'iseless as far as the operation olI the valve is concerned and in which jarring and vibration incident .to the operation thereof reduced to va minimum.

Our invent-ion maybe further briefly summarized as consisting in certain novel details of construction and combination and arrangement of parts, which will be described in the specification and setiforth in the appended claims. In the drawings Figure 1 is a side elevation of a motor equipped with our invention, showing also a portion of a washing n machine shaft which is operated thereby.

Fig. 2 is a. plan view of the same. Fig. 3 is an end elevation of the same. Fig. 4 isa section taken chamber.

Referring now to the figures of the drawing, 10 represents a base, which supports the motor and which is intended to be'mounted above or on the top' of the machine to be o erated, such as a washing machine.

ounted on the base are two cylinder heads `11 and 12 which support between the same the cylinder v-1 Passing through a suitable opening in the cylinder head llvand through the shaft is a gear through the valveand valve.l

carries at itsv inner in dottedlines in Figs. 1 and 2: the outer endol'4 the )iston rod 15 in such a piston is a rack bar 16'Whic extends along the side of the cylinder. parallel to' the piston rod'and is supported in a lugor extension .of the cylinder head 12. The base 10 is provided at one side .of the cylinder with apsuitable boss or bracket 17, in which is ljournaled the vertical shaft 18 of the machine to be operated. At the upper-end of` segment 19 which engages' L Patented sept..1,r19osv. p

a'stufiingbox 14, is a piston rod 1.5,l

end a piston 15" shown Secured tol .manner that itmay e reciplrocated by the the teeth of the rack-bar and intermediate` the segment and the top ofthe boss is a collar 20 which holds the shaft in position. Thus itw'ill be lseen that when the iston is o )erated the shaft 18 willy be oscil. ated by t e rack bar and segment.

.Between the base l0 and cylinder 13 is a l Valve casing 21 having a cylindrical bore-or valve chamber 22. Connected 'to one side of the valve casingare fluid supply and exhaust )i es 23 and 24, which communicatelil P with `t e chamber through inlet and outlet ports 25 `and 26, and 'extending in opposite direction from the valve casing are tubular projections -27 and 28, the former communieating with .the valve chamber through a port 29 intermediate the ports 25' and 26 and with one end ol' the cylinder through a passageway 30, which, as' here shown, is cored in the cylinder head 1], and the latter communicating with the valve chamber through a port 31 located diametrieally 0pposite the port 29 and with the 0 of the cylinder through a passageway 31 1n the cylinder head 12. .v v-

Located inthe valve chamber and mounted on a valve stein32 which extends through the side of the valve chamber opposite the supply and exhaust pipes is a rotary or oscillatory valve 33 the oppositeedges of which are curved and engage closely the inner cylindrical surface of the valve chamber. Secured to the outer end. of the valve'stem visa crank -34 provided with a wrist pin 35 [on which 1s mounted a sleeve' or ro ler 36 and opposite th-crank is an enlargement 37 forming a counterl weight thel purpose 'of which will be explained.` The roller 36 on .the pin 35 is,`engaged by a bifurcatedend of a valve operating lever 38 pivotally supported intermediate its ends by means of a transverse pin or lug 39 in a hub or` boss 40V opposite end hold or gripv to drive the same.

' same.

'. time undergone of an arm 41 integral with the bracket or boss 17 extending upward .from the base. The end of the lever Ais provided with a hand so that the motor can be operin case there should be n0 power Pivotally connected at 42 to the lever 33, and passing loosely through an opening, in an upwardly extending lug 43 on the rack bar, is a valve operating rod 44,l which is shifted by the rack bar in a manner to be explained and in turn opcrates the lever 38 and valve 33 to reverse the movement of the piston. Adjustably mounted on the'rod 44 are two collars 4 5 and 46, one near the` outer end of the rod and on one side of thelug 43, and the other on the opposite 'side of the lug 43. Surrounding the rod between the collars and the lug 43 are coiled springs 47 and 4S which serve to throw the valve at the .proper time, and also to cushion the b low of the rack bar upon the valve rod as will be explained.

The operation and purpose of the parts will new be explained more Jfully.

When .the valve' is in the position shown in Fig. 4 the motive fluid passes from the inlet or supply pipe 23 through ports 25 and 31 to the. pipe or tubular projection 28 and to the right hand end of the cylinder as shown in Fig. 1. At the same time the opposite end of the cylinder is connected to the exhaust pipe 23 through-ports 29 and 26. The piston is then driven toward the opposite end of the cylinder, shifting the rack bar i6, gear segment 1.9, and the operating shaft to which it approaches the end of the stroke the lug 43 engages thespring l48 and compresses the When the piston has the end of theA stroke theA spring has been compressed sufficiently to cause the valve rod and valve to be moved and. the counterweight to be raised toward the central vertical position. This movement of the valve however is comparatively slow as the spring is still undergoing compression is retarded. bythe counterwveight and also this movement of the valve is not sul'licient to cause theclosing of' the ports. When the piston has reached. the end of the stroke the cminterweight has been liftedto the central vertical position or approximately to that position, and the spring, which has by this l the maximum compression, expands, throwing quickly the 'counterweight. beyond its central position, and the valve is then shifted by the combined action c.' the spring and eounterweight with the nick movement so as to connect the supp y pipe 23 to the opposite end. of' the cylinder, whereupon the piston immediately begins its return stroke. lt will be seen that the only movement imparted to the valve directly bythe piston and rack bar, is that movement which takes place while ated by hand is attached. As thepist'on` nearly reached and the valve the spring is being compressed and the counterweight 1s being raised to the central posiwhich controls the motive the energy stored in the spring and also in the counterwe'ight. Thus it will be seen that it willbe impossible for the valve to stick and the motor to become stalled at the end of the stroke, since 'the valve is shifted quickly bythe spring and weight. It will also be seen that the impact of the rack bar on the valve operating ioned, hence jarring and vibration is lreduced to afininimum.

We de not desire to be conlined. to the l exact details shown but aim in our claims l to cover all modilications which do not involve the departure from the spirit and scope ol our invention. What we claim i,s,--

l. vIn combination, a cylinder, a piston in said cylinder, a rack bar operated by said piston, a rotary counterweighted valve controlling the motive lluid to'said cylinder, a valve operating mechanism comprising a lever connected to the valve stem, a valve l' rod connected to said lever, and springs on said valve rod, and means whereby the movement of the piston and rack bar causes the springs to be compressed and shifts the countcrweight to a position such that the springs may expand and shift the valve further With a quick movement. y

2. In combination, in a motor, a cylinder, a piston in said cylinder, a rack bar connected to said piston and adapted to be operated thereby, a vrotary counterweighted valve contrplling the motive lluid to said cylinder, a valve operating mechanism comprising a lever connected. to said valve, and a valve rod connected to said lever, springs on said valve rod and .means whereby the movement of y the piston and rack bar compresses a spring and shifts the valve and counterweight to a position such that the'spring iluid is caused by l l l tion and the main movement of the valve.
